cable 31 SDI Vision Ecoflex LSZH ST 4.5 The SDI Vision range of 75 Ohm precision coaxial cables comprises a Low Smoke Zero Halogen jacketed single coax and 6 way LSZH jacketed multicore. As with the Van Damme HD vision range close attention has been paid to their electrical characteristics and tolerances to ensure trouble free performance with SMPTE 259M SDI signals as well as analogue video. These cables can also be used for shorter distance transmission of 2.97 Gb/s HD-SDI - please see the transmission length guidelines. Applications Transmission of SDI and analogue video signals Short runs of 2.97 Gb/s HD-SDI 6 way multicore ideal for multiple SDI runs and/or RGBHV + composite analogue video Installation in public buildings, schools and colleges, government premises and marine vessels Application notes Use of precision 75 Ohm components throughout any signal chain is imperative Jacket material specied as the thermoplastic polymer SHF-1 compliant with IEC 60092 Electrical Installations in ships pt. 359 - Sheathing materials for shipboard power and communication cables Fully tested and compliant with the following IEC standards (see glossary for full description) IEC 60332.1 Fire retardancy of a single cable IEC 60754.1 Amount of Halogen Gas Emissions IEC 60754.2 Degree of acidity of released gases IEC 61034.2 Measurement of smoke density Transmission length guidelines These transmission lengths have been calculated throughout to a maximum attenuation of -30dB at the frequency corresponding to half of the actual signal data rate for SMPTE 259 and -20dB for SMPTE 292. SMPTE and others advise that 90% of this cable length introduces an appropriate safety factor- the chart below includes an 80% safety factor as jitter and other factors can increase dramatically in the last 20% of a cable run.SDI vision series SMPTE 259 SMPTE 292 SMPTE 424 Data rate (clock) 143Mb/s 177Mb/s 270Mb/s 360Mb/s 1.485Gb/s 2.97Gb/s 1 2 Clock Rate 72MHz 89MHz 135MHz 180MHz 743MHz 1485MHz Recommended transmission length 264m 237m 196m 172m 54m 36m Mechanical specification Conductor Material Bare ultra pure oxygen free copper Stranding 1 x 0.60mm Dielectric Material Foamed polyethylene Average thickness 1.10mm Diameter 2.80mm 0.05 Screen 1 Type 35m Aluminium/polyester foil 125% coverage Screen 2 Material Tinned bare ultra pure oxygen free copper Coverage 90% Dimension 16x5x0.16mm Overall Jacket Material SHF-1 LSZH polymer Water blue RAL 5021 Average thickness 0.40mm Overall diameter 4.50mm 0.15 6 way multicore Overall Jacket Overall jacket Material SHF-1 LSZH polymer Colour Water blue RAL 5021 Overall diameter 15.60mm 0.30 Bend radius 15 x overall diameter Physical properties unaged 2 Jacket (at 60C) Tensile strength >9 N/mm Elongation >125% Heat shock test 150 C x 1 hour no cracks Halogen Emissions 0.30% Halogen acid gases according to IEC 60754-2 Electrical characteristics Resistance Conductor <69 Ohm/Km Shield <10 Ohm/Km Insulation >5000 M Ohm/Km Voltage test 1500V DC 1 minute OK Capacitance 56 pF/m Velocity of propagation 80% Impedance at 10MHz 75 Ohms 1.5 Attenuation 5 MHz 2.84 dB/100m 200 MHz 14.70 dB/100m 10 MHz 3.92 dB/100m 270 MHz 17.15 dB/100m 100 MHz 10.72 dB/100m 400 MHz 21.12 dB/100m 135 MHz 12.24 dB/100m 743 MHz 29.77 dB/100m 180 MHz 13.93 dB/100m 1485 MHz 44.05 dB/100m Structural return loss dB 15 20 25 30 35 40 45 50 0 100 200 300 400 500 600 700 800 900 1000 1100 1200 1300 1400 1500 MHz Characteristics & description Stock code Description RAL code Weight Reel Kg/km lengths 278-075-000 Van Damme SDI Vision single coax LSZH Ecoex 4.50mm 31 500m 278-075-006 Van Damme SDI Vision 6 way multicore coax LSZH Ecoex 15.60mm 300 500m
